Blocking Your Tail Number

All blocking requests are handled by the FAA.

Two levels of blocking are available:

ASDI Vendor Level • Block at this level if you need to track your aircraft.

The FAA coordinates with all ASDI vendors to have your aircraft registration number blocked from their respective programs. Blocking the aircraft registration at the ASDI Vendor Level removes the aircraft registration from the aircraft flight data.

FAA Level • Block at this level if you do not need to track your aircraft.

For a higher level of security, operators may choose to block their aircraft flight data at the FAA Level which will remove all aircraft flight data before it is transmitted to the ASDI vendors. This means the information never reaches any ASDI vendor and is not incorporated into their system. Blocking at this level will prevent you from tracking your blocked tail number.

All blocking requests must include the following:

Aircraft owner/operator name and address.

Email address the FAA can use to communicate with the aircraft owner/operator regarding the blocking request.
